Trusted Sharing of IOT Data Using an Efficient Re-encryption Scheme and Blockchain

The major unit of Internet of things or IoT is data, and it is being used by IoT sharing system. It is necessary to develop a trust between sensor owner and sensor user. This research paper aims to provide solution to the following burning problems by providing the “dual” re-encryption methods: (i) scalability, (ii) trust, and (iii) digital payments. This method saves the data in a distributed cloud, when the encryption process is finished. A bridge has been developed in this work between the sensor owner and sensor user without any intervention.
